SCTP Packet
SCTP protocol packet consist of two main parts Header and Payload. The Header is common but Payload have variable chunks.
The Common SCTP header is 12 byte long and made of the 4 parts
- Port Number (Source): shows the sending port
- Port Number (Destination): shows the receiving port
- Verification tag: a 32 bit random value which differentiate the packets from the previous connection
- Checksum: a CRC32 algorithm for detection of error.
